I just bought a few of these. They have a bulk discount as well. Mine arrived yesterday. They are VERY fast and seem to be built about as well as anything. I copied this link from a thread that is only a few days old.

What are the length on those? I have members ranging in height from 4'11 to 6'5", and one of the problems I've had is finding jump ropes that are easily adjustable.

My current solution is to get a whole crapload of the $2.34 Target jumpropes (which actually work quite well, but they break frequently - usually in the middle of Annie!) and trim some of them down so I have a few in each of several lengths. Are these ones adjustable at all?

They are adjustable & super fast. I don't know if they'll work for someone 6'5, right out of the box they seem to be perfect for someone 6'1 to 6'0. They're so simple to make/repair that it wouldn't surprise me if the manufacturer cut a couple to a custom length for you.
